我正在使用芹菜来运行正在侦听某些Web连接并记录消息的任务。环境信息如下：
software -> celery:4.1.0 (latentcall) kombu:4.1.0 py:3.6.3 billiard:3.5.0.3
py-amqp:2.2.2 platform -> system:Linux arch:64bit imp:CPython loader ->
celery.loaders.app.AppLoader settings -> transport:amqp results:disabled
这些任务应该始终像我在async函数中使用true循环时一样运行，以保持Web服务器发送的记录消息。然而，几个小时后，所有芹菜任务都停止了。我发现我的芹菜工人的主要过程和子过程仍然在运行，但是子过程的开始时间比主要过程要新得多。

为什么子进程关闭并重新启动？ （芹菜的任务再也没有排队了。） 保持这些长期运行的任务永远运行的最佳做法是什么？ 任何帮助将不胜感激！
